The Data Science Workshop

By: Anthony So, Thomas V. Joseph, Robert Thas John, Andrew Worsley, Dr. Samuel Asare

Overview of this book

You already know you want to learn data science, and a smarter way to learn data science is to learn by doing. The Data Science Workshop focuses on building up your practical skills so that you can understand how to develop simple machine learning models in Python or even build an advanced model for detecting potential bank frauds with effective modern data science. You'll learn from real examples that lead to real results. Throughout The Data Science Workshop, you'll take an engaging step-by-step approach to understanding data science. You won't have to sit through any unnecessary theory. If you're short on time you can jump into a single exercise each day or spend an entire weekend training a model using sci-kit learn. It's your choice. Learning on your terms, you'll build up and reinforce key skills in a way that feels rewarding. Every physical print copy of The Data Science Workshop unlocks access to the interactive edition. With videos detailing all exercises and activities, you'll always have a guided solution. You can also benchmark yourself against assessments, track progress, and receive content updates. You'll even earn a secure credential that you can share and verify online upon completion. It's a premium learning experience that's included with your printed copy. To redeem, follow the instructions located at the start of your data science book. Fast-paced and direct, The Data Science Workshop is the ideal companion for data science beginners. You'll learn about machine learning algorithms like a data scientist, learning along the way. This process means that you'll find that your new skills stick, embedded as best practice. A solid foundation for the years ahead.

In the previous chapter on balancing datasets, we dealt with the Bank Marketing dataset, which had 18 variables. We were able to load that dataset very easily, fit a model, and get results. But have you considered the scenario when the number of variables you have to deal with is large, say around 18 million instead of the 18 you dealt with in the last chapter? How do you load such large datasets and analyze them? How do you deal with the computing resources required for modeling with such large datasets?

This is the reality in some modern-day datasets in domains such as:

  • Healthcare, where genetics datasets can have millions of features
  • High-resolution imaging datasets
  • Web data related to advertisements, ranking, and crawling

When dealing with such huge datasets, many challenges can arise:

  • Storage and computation challenges: Large datasets with high dimensions require a lot of storage and expensive computational resources for analysis...
